Cummins Diesel single clutch billet converter. Can be ordered with a billet clutch piston with a large oversize clutch. The billet CNC piston will not flex. This converter has a red lining that is 38% larger than a stock clutch. Can be ordered in a lower stall speed with the aluminum billet stator option. The increased power of a modified diesel engine raises the stall speed of stock converters, which is detrimental to vehicle towing performance and drivability. We now offers a low stall stator for Dodge diesel pickup truck owners who have increased the power output of their engines for added towing and general performance.
